The best spot on this Hiking segment, called Sabana Buthak/Sendang. There's spring so you can supply your water needs for your camping. The views is so gorgeous, especially when the sunrise & sunset come.
It's near to reach the top of My. Buthak from here & also there's vast area here so it's best to make it your campsite here before you go to the summit at afternoon for sunset or the next morning for sunrise.
The best time visit it is around summer (June-September). But prepare your sleeping gear such as Sleeping bag & warm clothes because the night so cold. The temperature can be down to below 0° when it reach the coldest time.
